Title: Triboelectric and Piezoelectric Nanogenerators for Self-Powered Electronics


Speaker: 김   상   우 교수님 (성균관대학교 신소재공학부)


Date & Time: Sep. 27. (Wed.) 2017, 4:30 PM


Place: Natural Science 1,  Room No. 31214


Abstract:

Energy harvesting systems based on piezoelectric and triboelectric nanomaterials are in great demand, as they can provide routes for the development of self-powered devices which are highly flexible, stretchable, mechanically durable, and can be used in a wide range of applications. Our recent research interest mainly focuses on the fabrication of piezoelectric and triboelectric power generators based on various kinds of nanomaterials. Flexible generators exhibit good performances and are easy to integrate which make it the perfect candidate for many applications, and therefore crucial to develop. In this presentation, I firstly introduce the fundamentals and possible device applications of triboelectric power generators, including their basic operation modes. Then the different improvement parameters will be discussed. As main topics, I will present a couple of recent achievements regarding highly stretchable piezoelectric-pyroelectric hybrid generators, transparent flexible graphene triboelectric generators, textile-based wearable triboelectric power generators, etc. The recent research and design efforts for enhancing power generation performance of generators to realize self powering of portable and wearable sensors and electronics will also be discussed in this talk. Additionally possilbilities for large-scale power generation using triboelectric generators will be discussed finally.
